A stock ZHP only puts about 200hp to the pavement. And with the wrong DME, you won't be able to take full advantage of the 3.0 motor anyways. A $100 set of headers and pullies would probably be about the same.
I have a ZF tranny and this is the same as the 330 I think.

For my 172HP thread please see my intake manifold retrofit project below

No, it's not the same as 330 transmission but it's rated for 250lbs of torque so you'll be fine.

Post your shopping list before ordering parts. It's easy to forget to order something and then having to wait another week for parts.

Flash, I don't get it

With all the money you've spent on modding the current 323, plus this engine, you could've easily afforded an S54 swap.

until I get the engine and start working on my car everything is a guessing game so I will try to keep my replies to a min.

In the mean time, can anyone can chime on my compression test question?
The MS42 and MS43/5 both have a seperate IAT on pin #20 and #21 of the X6003 connector (they even use thesame sensors)
The MS42 also has a mecanical throttle , the wire is just activationg the potentiometer on the TB (and serving as a failsafe if the MDK is somehow deactivated), on the MS43/5 the pot is on the pedal.
The MS43/5 doesnt monitor fuel pressure , doesnt really matter if you use the M52 or M54 fuelrail, the M54 will have more expensive filters and a longer vacuum line though

From what i can gather you need to crank the engine with the starter to get a good reading , preferably the engine should be warmed up too...

yes, you are right. I was quoted $7K for a complete S54 swap but I am taking on this project because I want the challenge. Of course the S54 is challenging but I think is way over my head if I do it myself (time and resources wise).

this is another subject in itself but I have been seriously taking about retrofitting the ZF 6 speed automatic (found on the twin turbo e9x) on the
M54 engine. It was already confirmed that the bell housing will mate with the engine block perfectly. what havent been confirmed is what modification is required for this to work (Tranny wire harness, TCU, drive shaft, etc)

They're really good trannys and I mean really good but unless you're dead set on needing an auto or want to be the first to do it the zf 5 speed manual found in early 330s and 328s are pretty much bullet proof with almost no power ceiling (sic) and would be a much easier swap and upgrade from your current 323 zf 5er. Espically should you choose to ever go fi on the b30 or even get into decently modding it they can pass that 250 torque ceiling on your current one pretty easily.

About that compression test. You can easily rig the starter to the engine using (2) 1/2 inch drive 12mm or 13mm sockets and small thin piece of scrap metal. And hot wire the starter as previously stated.

You won't be able to spin it fast enough by hand to build good compression.

My Ride: cars older than you
I look forward to seeing how this turns out. If you decide to give up on this I might pick it up from you for my project car. Think of a 1969 3002 (actually I want a S50B32 for a swap... wouldn't that be nice)

The ZHP engine has about 90,000 miles.

Planning to do the VANOS seal, vanos rattle and change out all the gaskets.

I am planning to run my original injectors, MAF, throttle body (mechanical), and DME (sharked).

Of course I will get it DYNO after the swap and report back. Currently my car has about 172HP (Dynojet) so I am very anxious to see how many ponies I will see after the swap.

More to follow. the update will be slow because I have to wait for the engine to arrive but I will start updating with pix and of the build as soon as I get the parts.

so excited!!!
Good luck! If it works out I'll attempt the same project!

http://forum.e46fanatics.com/showthr...ghlight=intake
I am curious what dyno that was on and if that is corrected power (SAE). I can't figure out how a car with factory 170hp at the crank with an AUTO trans (figure 20-30% loss through the drivetrain) is able to put 170hp to the wheels. A stock ZHP with a 6MT makes 235 at the crank and only gets 200ish to the wheels.

So you are going to go through a lot of pain and anguish to gain 30whp. It would be easier to pick up a used SC kit and bolt it on. I am all for retrofit projects, but this one makes little sense to me. But if you enjoy it, what the heck, go for it right?

One other thing to think about, the 330's come with larger axle splines, I doubt you'll have problems, but it is another potential weak point. And given that the ZF trans is more problematic and weak than it's GM counterpart, I'd strongly suggest a 5 speed swap.

It just take a minute to read the thread that I posted especially since you questioned (time and time again) my result. I posted my "rebuttal" but yet you continue to ask me the same question. It seems like you are one of those type that are set on your ways and refuse to believe/hear/see any counter arguments that might proof you wrong.

Did x3 dynojet runs each with 4-5 pulls.

each runs consistently pull over 16x ponies.

here is the spec you are asking. again, it just take a minute to read the thread
SAE correction 1.04. SAE Smoothing 3

As I read through this thread I was thinking the same thing.... read and you may learn something.

Many people are questioning why you are doing this swap for minimal gains, but they are forgetting that this is just a new starting point with a larger platform. Judging by your previous work this will not be the last mod and there will be much larger gains in your future with this new platform.

If I were to do this swap I would not do the drive by wire conversion either, I personally would much rather keep it mechanical and skip all of the problems that are going to come with trying to retrofit drive by wire.

You need not get so defensive. If you don't see why I am questioning you then re-read my posts. I didn't say I didn't believe you.

Mini update: the engine is coming on 17jan. We already bought a cherry picker and an engine stand. Oh yeah....scored a great price on a used zhp cluster. Going to erase the EPROM chip and encode it with my vin and mileage.

Tonight I will post pictures of the engine stand and cherry picker

1000lbs engine stand
2 ton cherry picker



also...painted some parking strips in the garage (oil based paint). Need to clear coat the strips with eproxy but still waiting for the oil based paint to dry. 1 week of drying/curing time should be okay






used cluster


very confident that I can transplant the EPROM chip from my old cluster to the new cluster or just erased the EPROM all together

Enjoy the new project! Someday when I have a backup DD I'll have a go at an engine swap up to the S52, I'm too emotionally attached to my 330Ci to give it up for an M3. You're my hero for doing a swap.

Nice setup, the engine stand is well worth it. Do the rear crankshaft seal before you put it on the stand.
I admire your confidence with car electronics. I wish I was this brave
